1. What happens to the kinetic energy of an object when its mass is doubled?

• A. Kinetic energy remains the same
• B. Kinetic energy halves
• C. Kinetic energy doubles
• D. Kinetic energy quadruples

Correct answer: c

Rationale: Kinetic energy is directly proportional to the square of an object's mass when its velocity remains constant.

2. The largest lymphatic vessel in the body is responsible for draining lymph from most of the body. What is it called?

• A. Jugular vein
• B. Thoracic duct
• C. Subclavian vein
• D. Aorta

Correct answer: B

Rationale: The correct answer is B: Thoracic duct. The thoracic duct is the largest lymphatic vessel in the body and is responsible for draining lymph from most of the body. It collects lymph from the left side of the head, neck, chest, abdomen, left arm, and lower extremities. The jugular vein (A) is a major blood vessel that drains blood from the head. The subclavian vein (C) is responsible for draining blood from the upper extremities. The aorta (D) is the main artery that carries oxygenated blood away from the heart. Therefore, the thoracic duct is the correct answer for the largest lymphatic vessel in the body.

3. You design an experiment to test the effectiveness of a new fertilizer. Which of the following factors would be considered a dependent variable?

• A. The type of fertilizer used
• B. The size and age of the plants
• C. The amount of plant growth observed
• D. The cost of the fertilizer per unit

Correct answer: C

Rationale: The dependent variable is the factor that is being measured or observed in an experiment. In this case, the amount of plant growth observed is the variable that is being influenced by the independent variable, which is the type of fertilizer used. The size and age of the plants (option B) could potentially be controlled variables, while the type of fertilizer used (option A) is the independent variable being tested. The cost of the fertilizer per unit (option D) is not directly related to the plant growth being measured in this experiment.

4. Choose the most appropriate word to complete the sentence "He was _____ about his upcoming presentation."

• A. apprehensive
• B. bored
• C. excited
• D. relieved

Correct answer: A

Rationale: "Apprehensive" implies a mild worry or nervousness, which best fits the context.

5. She plans of assigning competent people to fill the roles designed in the hierarchy. Which

• A. Staffing
• B. Scheduling
• C. Recruitment
• D. Induction

Correct answer: B

Rationale: The correct answer is B: Scheduling. Scheduling involves assigning people to specific tasks or roles within an organization based on the hierarchy and operational needs. In this scenario, the focus is on assigning competent individuals to fill the roles outlined in the hierarchy, which aligns with the concept of scheduling. Staffing refers to the overall process of acquiring, deploying, and retaining a workforce; recruitment specifically pertains to attracting and selecting candidates for job roles; and induction involves the orientation and integration of new employees into the organization. Therefore, the most relevant term in this context is scheduling.

6. Which phenomenon describes the bending of light as it travels from one medium to another with differing densities?

• A. Reflection
• B. Refraction
• C. Diffraction
• D. Dispersion

Correct answer: B

Rationale: The correct answer is B: Refraction. Refraction is the phenomenon that describes the bending of light as it travels from one medium to another with differing densities. When light passes from one medium to another, such as from air to water, its speed changes, causing it to bend. This bending of light is what we observe when a pencil appears bent in a glass of water. Reflection, on the other hand, is the bouncing back of light when it hits a surface. Diffraction refers to the bending of light around obstacles, and dispersion is the separation of light into its different colors. Therefore, in this case, refraction is the most appropriate term to describe the bending of light as it moves between media with different densities.
